%X By means of embedding Java Applet in Web page, dynamic displaying frequency response of discrete-time system is realized. Responding mouse events are used in order to vividly depict the influence of the positions of zeros and poles on frequency response characteristic and the idea of layer map in interface design is put forward. The program has shown originality in the dynamic property, interactive property and interface design, etc. This is also a beneficial trail in how to teach Signal & System on the Web.
